A police constable was beaten up by the family members of a local BJP politician for imposing fine on their two relatives for violating traffic rules, said a police officer today.

Guna police station in-charge Vivek Asthana said the police subsequently arrested two persons on charges of assaulting a government official on duty and obstructing him from discharging his duty.

Asthana said the beating incident, captured on cell phone camera, occurred on April 21 when a police team stopped two girls, the relatives of BJP Janpad (Block) president Shobha Raghuvansi, for riding a scooter without helmets.
